If there’s something you’re excited about using, pick that product and build from there. Don’t just buy a product because you’ve heard about it, but rather something that you're really motivated to use.
If you’re limited to one thing, Mosaic recommends going with a smart speaker. “Start with a voice platform and try it out," says Torres. "That way you don’t have to spend money on other devices, and you get a sense of how to interact with it.”
Choosing that product will also determine the ecosystem that controls your entire smart home. NXP's Azevedo suggests, "Choose a preferred ecosystem of devices like Apple’s Home Kit or a hands-free controlled device compatible with Amazon Echo. Because one smart device may not necessarily work with the other, choosing a system or ecosystem you’re comfortable with is key to ease installation and compatibility for the rest of your devices."
